DS9503 diode equivalent, esd protection diode.
* Zener characteristic with voltage snap
–back to protect against ESD hits
* High avalanche voltage, low leakage and low capacitance avoid signal a.
This DS9503 is designed as an ESD protection device for 1
–Wire MicroLAN interfaces. In contrast to the DS9502, the DS9503 includes two 5isolation resistors on chip. Although 5are negligible during communication, they represent a h.
